摘要:
A propeller formed along the lines of a vortex, i.e. a Fibonacci spiral projected onto a surface formed by a square hyperbola. Fluid flows evenly along the length of the propeller with less turbulence allowing it to operate at a higher pitch without stalling and resulting in reduced power requirements for a given flow rate. The underlying geometric shape of a vortex is an equiangular logarithmic spiral also known as golden spiral or Fibonacci spiral as is often found in natural objects ranging from sea shells to spiral galaxies. When viewed three dimensionally, the fluid flow in a vortex can be drawn as a projection of a golden spiral onto a surface of revolution of a square hyperbola where the vertex is equal to one and the focus is equal to the square root of 2.
摘要(中):
沿涡流线形成的螺旋桨,即投影在由平方双曲线形成的表面上的斐波纳契螺旋线。 流体沿着螺旋桨的长度均匀地流动,具有更少的湍流,从而允许其以更高的间距操作而不停顿,并且导致给定流量的功率要求降低。 漩涡的基本几何形状是一种等角对数螺旋,也称为金色螺旋或斐波纳契螺旋,通常在海贝壳到螺旋星系的自然物体中发现。 当三维地观察时,涡流中的流体流动可以被绘制为金色螺旋的投影到方形双曲线的旋转表面上,其中顶点等于1,焦点等于2的平方根。
